Improvement in street-washers



UNITED-STATES PATENT OFFICE.

JOHN MOOLELLAND, OF WASHINGTON, DISTRICT OF COLUMBIA.

IM PROVEM ENT IN STREET-WASHERS.

Specification forming part of Letters Patent No. 58,857, dated October 16, 1866.

To all whom it may concern:

Beit known that I, JOHN MOCLELLAND, of the city of Washington, in the District of Columbia, have invented certain new and useful Improvements in Street- Washers; and the following is a clear, full, and exact description of the same, reference being had tO the accompanying drawings, making part of this specification, in which- Figure l represents the outside of the cap, the water-pipe, the pipe that incases the rod that operates the stop-cock, and the case that protects the same. Fig. 2 shows a vertical section through the whole apparatus and inode of Operating the same.

The object of my invention is to construct metallic streetwashers so that they may be set and secured so firmly in the ground that the frost cannot lift or move them out of their places.

My invention consists in making a 'flanged metal case of just sufficient size to cover the cock that regulates the iiow of water, and a metal cap to be placed above the pavement, the cap being connected with the ironflanged metal case and the brass stop-cock by means of iron water-pipes of any desired length or size, they having a right and left screwfthread on each end for that purpose.

To enable others skilled in the art to make and use my invention, I will describe it more fully, referring to the drawings and the letters marked thereon.

I make the stop-cock A of my improved pattern for which l have obtained Letters Patent, and cover it with the ease B, the interior of which is only of sufcient size to contain it.

The case B may be made oval or conical at the bottom, but flat, or nearly so, On the tcp, where the pipes C and E pass through it, and are screwed into the cock A near the top of the case B. On the outside is a broad iiange, E E, which extends all the way round the ease, for the purpose of securing this portion Of the apparatus firmly by tampin g the earth Or sand upon it where the street-washer is being set.

The pipe G, through which the water flows,

is screwed into the cock A, as seen at a a in Fig. 2, and extends up into the cap F, where it is made fast by the under-side nut f and the brass screw-socket b b, On which the hose is screwed for street-washing.

There is another piece of common waterpipe, D,of larger dimensions, which is screwed into the stop-cOck A, as seen at e e, which stands parallel with the water-pipe O. This also connects the stop-cock with the cap F, by having a left-handed screw-thread, d d, cnt upon its upper end, and the hole in the cap being tapped to fit it.

Through the pipe D the key-rod G connects with the plug 7L of the stop-cook A, by which it is turned to let on or shut off the flow of water.

Thus it will be seen that-the case for the key-rod is entirely independent, and is separate from the water-pipe, so that the one is not affected by the other.

The past winter has fully demonstrated in this and other cities that the frost lifts the metallic street-washers by the hold it takes upon the sides of the iron cases, and not from the bottom, and therefore the less surface Of iron near the top of the ground the less chance there is for the frost to get hold on. Hence, by leaving the pipes C and D without any casing, and the flanged case B being tamped in hard so low down below where the frost can reach, there can be no possible danger or liability for the street-washer to be raised and sever its connections with the main pipes.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The short case B, as constructed, in combination with the stop-cock A, pipes C and D, top plate or cap F, and key-rod G, as described, for the purposes herein set forth.

2. The iianges E E on the case B, which covers thestop-cock A, to prevent it from being moved or lifted up by the action of the frost from the top, as described.

JOHN MOGLELLAND.
